The Basics of Blockchain and Its Mission to Secure the Healthcare System



Your health should not have to wait in line to get checked up. How often do you find yourself going back and forth between your family physician, then to the laboratory for a blood test, and back to your doctor for another check up? Not to mention waiting in the dreary room even though you had your appointment booked days in advance. The amount of hours this process takes eventually leads people to postpone their health when in fact it should have been taken care of immediately.  

Well, that is where the savior concept of blockchain comes in, and it’s crucial for everyone to understand what is up-and-coming. Before any discussion can be held on the application of blockchain, we must have a clear definition of what blockchain is and how this concept applies to your healthcare needs.

An Easy Understanding of Blockchain for Beginners

In the past several months, recent news articles have been hyping up the legitimacy of applying blockchain methods to other industries, and one of biggest areas is the Healthcare Information Technology (IT) sector. The blockchain is the new foundation of the Internet for over a decade. It derived from the idea of bitcoin, which is a digital currency method that has close to $112 billion in value in the United States. Now, the tech community has expanded the value of economic transactions that are made virtually. Basically, blockchain has become the foundation of the new type of Internet, and it’s a revolution for incorruption and systemic efficiency.

The blockchain is simply another type of cryptocurrency such as the bitcoin. It is like a public ledger system where individuals can record their transactions; in regards to healthcare, these transactions are datasets such as blood tests, surgeries, implants, insurance information, and more. Each transaction is a “block” (hence the title of blockchain) and the blocks are added to other existing blocks until it creates a “chain”. Once each block is verified and approved, it is added to the public log and remains permanent.

If you still don’t know how it works, that’s okay. You actually don’t need to know the specific technicalities of how it works to use it, just like the Internet.

Basically, blockchain has become the foundation of the new type of Internet, and it’s a revolution for incorruption and systemic efficiency.”

Let’s put this concept from the perspective of a NBA basketball game. There are generally two teams, a scorekeeper, and a referee. All players must unanimously agree on the rules beforehand so that no one is cheating or making foul plays. Fans are watching the game and can help maintain the system to keep it in check.

Analogous to blockchain, each block is the score and all the fans and spectators help keep them in check of the rules. To reward those who help keep accurate scores, now fans can get rewarded for keeping the system updated and in check. Whoever is the first to correctly verify and approve the score (or “block”) will get rewarded for contributing to the public log system. Now, even though the fans are not the actual million dollar basketball players, they have the opportunity to gain benefits for their contribution to the overall score.

Same as the cryptocurrency, users who are not even involved in the transactions but also part of the blockchain node also keeps track of transactions as well and record their own blocks. The way logs across the system remain exact copies of each other as new blocks are updated and added is through solving a sort of computational math puzzle.

The Impact of Blockchain on Healthcare

The impact of blockchain could potentially have on the healthcare sector are numerous. It has a high potential to generate easier access and sharing of information for healthcare records. More time will be saved with the accessibility to track and ship for supply chains. Blockchains can also aid in the medical recording by providing an immutable medical record that cannot be changed, aiding in any legal cases in which an untampered medical record is needed. Patient records can be consolidated into a single record; lab results, treatments, disease registries, treatments, etc. can all be compounded together to give a holistic view of patient history so that providers can plan better strategies of healthcare. You will no longer find yourself wasting time back and forth between each lab and all your data will be in one safe place.

List of blockchain benefits:

  • Patient data sharing issues can also be addressed across state borders, where regulations regarding patient privacy and consent vary from state to state.
  • Permission checking will keep patient data secure while granting easy information access for other permitted parties to view. It can also assist in settling payments between insurance providers, hospitals, and patients.
  • Patients can be also incentivized and rewarded from following a care plan, following appointments, and staying healthy through the blockchain system.
  • Patients may also be rewarded for sharing their data with clinical trials and research.

The Reality of Blockchain

Blockchain definitely has its ups, but those come with its downsides. It is not designed for the use of analytics. Blockchains has issues with transactional performance; for example, bitcoin runs at around 7 transactions per second. To put in an easier context to understand, 7 transactions is almost nothing compared to something like VISA, where around 24,000 transactions are recorded per second! It has problems with large data storage over time and scalability issues. Because the logs have to be recorded, it can lead to large numbers of information that gets repossessed, leading to high inefficiency costs. Greater research is still ongoing to optimize data transfer within blockchain.

If the problems currently facing blockchain can be resolved, then we may be able to enjoy faster and more efficient healthcare in the future. There wouldn’t be a need to wait in line at the doctor’s office while the office workers call various providers and to see if you are qualified to receive care. Doctors would be able to streamline your personal healthcare plans by having access to your past healthcare plans and plan accordingly to how different methods have worked and what new steps could be taken. You can be more involved in your own health by having up-to-date biometrics data, monitoring your own progress, and keeping up a routine of visiting your healthcare provider on a regular basis.

A Look Into Health IT and Patient Safety



Over the last decade, health information technology (HIT) has had a significant influence on patient quality of care and safety. HIT is defined as “the application of information processing utilizing computer software and hardware that will process, store, and retrieve data for decision making” and knowledge sharing. The technology aims to reduce human errors, improve care coordination, and enhance clinical outcomes for patients. Here are some examples of existing technologies that have changed the healthcare landscape: 

  • Electronic Physician’s Orders: In this process, physicians utilize electronic or computer support to enter medication orders. More robust systems also allow physicians to order consultations, tests, and procedures. Electronic Physician’s Orders have been interlinked with the clinical support decision systems (CDS) to ensure the safety of clinical orders. This is done by preventing drug dosage and administration errors. A metanalysis suggests that this process been found to reduce medication errors and severe drug reactions effectively. 
  • Clinical Decision Support: This form of support is meant to relay patient-related information to the healthcare provider to optimize clinical decision making. The tools that assist in clinical decision making include notifications, clinical guidelines, patient clinical summaries, and other documentation. Research has concluded that compliance with on-screen physician reminders resulted in small improvements in process adherence, medication orders, and different clinical outcomes. 
  • Bar Code Medication Administration: Bar code technology is integrated with electronic medical records to ensure that patients receive the correct amount of medication. Advanced software has special medicine validation features that can provide alerts if there is look-alike medication. This technology has reduced medication administration errors by 50% to 80%

While there is substantial evidence that health information technology plays a role in patient safety, it is essential to receive front-line and executive buy-in. Buy-in will allow the organization to be fully equipped to reap the benefits of the technology.
